Embodiment 1

[0011] Get 200 grams of disperse dye filter cake (about 50% solid content), put it into a container, add 700 grams of water, then add 100 grams of commercially available MF dispersant, and stir to form a slurry. The container matching the FM200 laboratory high-shear mixing and emulsifying machine produced by Shanghai Fluke Fluid Machinery Manufacturing Co., Ltd. and the JY98-III ultrasonic cell pulverizer produced by Ningbo Xinzhi Technology Co., Ltd. are connected through pipelines. Form a recirculating loop, which can be realized by connecting a water pump to the pipeline. Pour the prepared slurry into the container of the circulation loop, and turn on the water pump to circulate the slurry, and then turn on the high-shear mixing emulsifier and ultrasonic cell pulverizer to make mechanical dispersion and ultrasonic dispersion proceed simultaneously. After 5 hours, the superfine disperse dye slurry was obtained, and the particle size of the disperse dye particles was determin...

[0015] The container matching the FM200 laboratory high-shear mixing and emulsifying machine produced by Shanghai Fluke Fluid Machinery Manufacturing Co., Ltd. and the JY98-III ultrasonic cell pulverizer produced by Ningbo Xinzhi Technology Co., Ltd. are connected through pipelines. Form a recirculating loop, which can be realized by connecting a water pump to the pipeline. Get 1000 grams of slurry after filter cake sanding in the conventional disperse dye production process, pour it into the container of the circulation loop, and turn on the water pump to circulate the slurry, then turn on the high-shear mixing emulsifier and ultrasonic cell pulverizer to make Mechanical dispersion and ultrasonic dispersion are carried out simultaneously. After 5 hours, the superfine disperse dye slurry was obtained, and the particle size of the disperse dye particles was determined to be 10-100 nanometers.

Abstract

Disclosed is a superfine dispersion method for dispersed dye, wherein dispersion dyes are subject to mechanical dispersion and ultrasonic wave dispersion simultaneously in an aqueous environment, the dispersion dyes are the end product of filter-pressed filter cake or sanded filter cake or dried grout of the original dyes during dispersion dyes manufacturing process, and dispersing agent is charged into the filter cake during the process of mechanical dispersion and supersonic wave dispersion.

Description

technical field [0001] The invention relates to a disperse method for disperse dyes, in particular to an ultrafine disperse method for disperse dyes. Background technique [0002] Disperse dyes refer to a class of dyes that are dispersed in a dye bath in the presence of a dispersant. The molecule contains polar groups, but does not contain water-soluble groups such as sulfonic acid groups and carboxylic acid groups. Disperse dyes dissolve very little in water. Disperse dyes are used for dyeing and printing synthetic fibers such as polyester, polypropylene, nylon and spandex. Closely related and the most used of all dyes. [0003] The raw dye of the disperse dye obtained after the reaction is press-filtered to obtain a filter cake, the filter cake is sand-milled to obtain a slurry, and the slurry is spray-dried to obtain a finished product of the disperse dye. Among them, the sanding process determines the particle size of the finished disperse dye. The particle size of th...
